Hello list,
As per discussion with Richard Purdie and others, I'm submitting a patch to
suppress some unnecessary invocations of utilities from the Texinfo suite during
Yocto builds. Specifically, it targets -native and -cross recipes that inherit
texinfo.bbclass.
The Texinfo utilities are suppressed by supplying doppelgänger executables which
understand the same command-line options as the genuine Texinfo utilites, and
which can create blank output files where expected, but which do no actual
processing, formatting, or markup. To see how this is done, look in the
texinfo-dummy-native recipe (under meta/recipes-extended,) added in this patch
series, as well as the modifications to texinfo.bbclass, also in this patch
series.
Suppressing the Texinfo utilities for -native and -cross recipes does provide a
noticable performance gain, as documented in bug 2421. [1] You could make the
case that this patch series still does not completely address bug 2421, as there
are other utilities not from the Texinfo suite (groff, pod2man, etc) which are
not suppressed by these changes.
Target-architecture recipes continue to use the host system's Texinfo utilities
as before, so that dependency is not eliminated by this patch series.
Regards,
-Max Eliaser

Allow texinfo, texinfo-native recipes to build w/o host system's
Texinfo utils
Add texinfo-dummy-native recipe w/ scripts to stand in for Texinfo
utils.
native/cross recipes use texinfo-dummy-native; target arch use host's
Texinfo.
